NSA 310 issue: CPU 100% for a week now

Post by nmliz » Wed Oct 26, 2016 9:53 pm


I have been using an NSA 310 for a couple of years now with no problems. I believe I recall upgrading the firmware about a week ago--it is 4.70(AFK.3)--although it seems to me that it has been running 4.70 for a long time.

Now the CPU has been at 100% for a week, and I am unable to access the shares from my PC (Win 7). I can access the admin page.

The HDD is fairly full (90%, or 2.41 Tb of 2.69 Tb total), but there are still 280 Gb free. SMART status is fine. Zyxel memory is only at 56%. I have tried restarting, with no change.

Could it be regenerating all the thumbs? Why? Could it really take a week?

Is there a way to roll back the firmware, or do I have to go all the way back to a hard reset?

Relative novice here, so please be kind.

If you go to the admin status display you will see the CPU usage, temperature, etc. displayed. Right next to the "CPU Usage" there is a green arrow and list icon. Click on that and it will pop up an information window with a list of that is running. Check out what is the top process on the list. I am sure that will be a start to figuring out what is happening.

Are you running Twonky for media? it may be re-indexing all your photo/video/music collection.

If you "Shutdown" and reboot does it still report high CPU?
